A central goal of topological photonics has been to develop compact isolators using protected, non-reciprocal edge states. A recent demonstration of a ferrite-based microwave isolator leverages the magnon-induced topological photonic bandgap to achieve over 100 dB of isolation in a device smaller than a single free-space wavelength.
A new imaging platform combines a high-speed, multichannel camera system with an iterative spectral unmixing algorithm, enabling high-resolution imaging of up to seven distinct fluorophores, even under challenging live-cell conditions.
Electrically induced single-photon emission and spin initialization of a silicon T centre in photonic structures is a promising step towards integrated spin–photon interfaces for quantum networks.
Thermodynamic-like phenomena in optics are a nascent yet elusive route to control light flow. By emulating Joule–Thomson expansion in synthetic photonic lattices, it is now possible to funnel light universally into a single output, regardless of the input.

Shaping the polarization state of ultrashort pulses in the extreme ultraviolet (XUV) range is challenging, owing to the lack of suitable materials for controlling the phase of the radiation. However, an approach using seeded free-electron lasers operating in the XUV wavelength regime now makes it possible to synthesize pulses with spatially dependent polarization states.
